摘要
以1
1′-双[2-(三乙氧基硅基)乙基]二茂铁(BTEF)和正硅酸乙酯(TEO S)为前驱物
经溶胶-凝胶过程(NH4F为水解聚合催化剂)制备了二茂铁桥联聚倍半硅氧烷修饰的玻碳电极(BTEF/TEO S/GCE).采用循环伏安法研究了BTEF/TEO S/GCE修饰电极对尿酸(UA)的电催化氧化.结果表明:在0.1 m o l.L-1N aC lO4磷酸盐缓冲溶液(pH=11.0)中
没有除氧的条件下
UA有良好的电化学响应;修饰电极上UA的氧化峰电位比在裸电极上降低了28 mV
峰电流增大;修饰电极呈现出良好的重复使用稳定性
连续扫描50次
峰电位没有变化
峰电流仅下降了5.2%.
Abstract
Ferrocene-bridged polysilsesquioxanes modified glassy carbon electrodes(BTEF/TEOS/GCE) were prepared via a sol-gel process of co-hydrolysis of 1
10-bis ferrocene(BTEF) and tetraethoxysilane(TEOS).The electrocatalytic oxidation of Uric Acid(UA) was characterized by cyclic voltammogram(CV) in 0.1 mol·L-1 NaClO4 aqueous phosphate buffer solution(pH=11.0) on the BTEF/TEOS/GCE.The UA has a better electrode response under aerobic condition.Oxidation peak potential of UA in modified electrode is decreased by 28 mV than in bare electrode
and peak current is increased.The BTEF/TEOS/GCE has better stability in the 0.1 mol·L-1 NaClO4 aqueous phosphate buffer solution.After 50 times scans
the peak potential remain unchanged and the peak current only decreases 5.2%.
